## FaceBook源代码泄漏 ##

据 [TechCrunch][]的消息称，FaceBook源代码遭到泄漏，并且已经被发布到名叫 [Facebook Secrets][] 博客。一般而言，源代码泄漏发生存在两种情况：其一是内部源代码开发者泄漏，另外一种就是利用程序的漏洞从而获取源代码。

登录该博客我们可以看到只是简单的几行代码，虽然不十分确定这就是FaceBook的源代码，然而让人担心的是成千上万用户的私人资料是否也安全呢？这对于Facebook来说无疑是致命的一击！

下面是该博客站点贴出的FaceBook首页源代码。

上午从TC看到[FaceBook源代码遭泄漏][FaceBook]，刚才去看TC的该页面，已经做了两点更新，下面跟大家分享一下：其一是FaceBook的Brandee Barker在评论留言中解释了一下造成此事的原因，另一件就是该文章作者Nik Cubrilovic在自己的博客上给出了预防PHP源代码泄漏的方法。

先说说第一件：FB官方给出的解释是，少数用户利用某台服务器的配置错误将源码泄漏出来，并且现在已经修复了此错误，且声明这不是安全缺口所以对用 私人数据并不会造成影响。不管是服务器配置错误或者符合超载，看来造成此事的原因是apache和mod\_php将未经解释的源代码直接输出。（原文）

> Some of Facebook’s source code was exposed to a small number of users due to a bug on a single server that was misconfigured and then fixed immediately. It was not a security breach and did not compromise user data in any way. The reprinting of this code violates several laws and we ask that people not distribute it further.

第二件Nik在博客上写了[四条预防PHP源代码泄漏][PHP]的方法：

1）使用[mod\_security][mod_security]过滤输出严防泄漏 Use mod\_security to filter output and prevent leakage （例如）

![None.gif][] PHP代码  
![None.gif][]  
![None.gif][] 1 .  SecFilterOutput On  
![None.gif][] 2 .  SecFilterSelective OUTPUT  " <?php "  log , deny  
![None.gif][]  
![None.gif][]

2）不要将关键敏感代码放到根目录中 Code should live outside of the web root （例如）

![None.gif][] PHP代码  
![None.gif][]  
![None.gif][] 1 .  index . php :   
![None.gif][] 2 .   
![None.gif][] 3 .  <? php  
![None.gif][] 4 .  include ( ' ../realroot/index.php ' );  
![None.gif][] 5 .  ?>   
![None.gif][]  
![None.gif][]

3）更改默认的文件类型 Change the default file type （例如对http.conf做如下修改）

![None.gif][] PHP代码  
![None.gif][]  
![None.gif][] 1 .  httpd . conf :   
![None.gif][] 2 .   
![None.gif][] 3 .  DefaultType application / x \- httpd \- php  
![None.gif][]  
![None.gif][]

4）绝对禁止访问根目录 Deny all outside of the webroot （假设你的根目录是 ‘www’ ，例如）

![None.gif][] PHP代码  
![None.gif][]  
![None.gif][] 1 .  http . conf :  (or  . htaccess)  
![None.gif][] 2 .   
![None.gif][] 3 .  < directory  />   
![None.gif][] 4 .  Order Deny , Allow  
![None.gif][] 5 .  Deny from all  
![None.gif][] 6 .  Options None  
![None.gif][] 7 .  AllowOverride None  
![None.gif][] 8 .   
![None.gif][] 9 .  < directory  / www >   
![None.gif][] 10 .  Order Allow , Deny  
![None.gif][] 11 .  Allow from all  
![None.gif][] 12 .  </ directory >   
![None.gif][]
